RECONDI'IIONING MACHINE.

Application filed May 17,

Thisinvention relates to new and useful improvements in a r conditioning machine.

An object of the invention is to provlde a machine of the character described specially designed for the purpose of cleansing, disinfecting and reconditioning mattress liller. ll'lattressesare usually tilled with lint cotton, and after a long period of use the iillerbccomes matted, or packed and also collects dirt and other foreign matter. This tiller cannot be cleansed and renewed by washing or scouring in water, as if sowashed or scoured it will lose its soft flLlllYlTGXtlllfG which, when lost, cannot be recovered, and consequently its use It is the prime object of this invention to provide a device for so treatng this used tiller that it will be thoroughly cleansed and disinfected and its life restored, resulting in a renewed. product having its original soft and lilutly properties.

Another objectof the invention is to provide a device of the character described which is of simple structure, may be cheaply and. easily constructed and which is very efficient tor the purposes intended.

it. further feature of the invention resides in a novel process of treating a used. mattress filler in the reconditioning and renewing thereof.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illus trated in the accompanying drawings wherein s Figure 1 device.

Figure 2 shows a vertical cross sectional view taken on the line 2-2 of Figure 1.

Figure 3 shows a vertical sectional view taken 011 the line 3-3 of Figure 2.

Figure 4: shows a partial horizontal sectional view taken on the line k4: of Figure 2.

Figure 5 shows a fragmentary vertical sectional view of the curing, or drying, chamber, and

Figure 6 shows a plan view of one of the foraminated shelves employed.

Referring now more particularly to the draivings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates a cabinet, as a whole, which is of a box like structure and which has a central. partition 2 separating the same shows a perspective view of the 1925. Serial no. erases.

into a treating, or steaming, chamber 3 and a drying, or curing chamber d. Corresponding ends of these respective chambers are hinged to the cabinet forming the doors 5, (i.

In the steaming chamber 3 are the upstanding steam manifolds 7, 7, one on each side approximately midway between its ends. These manifolds are connected, at their lower ends,into the steam supply line 8, which is controlled by the valve 9. Each manifold has the steam nozzle pipes 10 extending therefrom in opposite directions, said nozzle pipes being spaced apart along the manifolds from the upperto the lower ends thereof, and lying adjacent the partition 2 and the opposing wall. of the steaming chamber. Each nozzle pipe has an inside row of nozzle openings 1.1 slightly inclined upwardly so as to direct the steam issuii'ig through them inwardly and upwardly, as shown in Figure 2. Located between the respective nozzle pipes 10, and an ranged one above the other are the removable foraminated shelves 12 whose side ma gins aresupported on the side ledges 13 whose rear cnds are anchored to the rear wall of the chamber 3 and whose forward ends are secured to the standards 14.

The :[iller to be treated placed on the shelves, outside of the cabinet and the loaded shelves are then inserted into place on the respective ledges 13. Hot steam is then applied by opening the valve 9. This steam is discharged under high pressure against the under side of the respective shelves and passes up through the shelves and the filler thereon, and said filler is throughly penetrated, cleansed and disinfected by said steam.- The expansion of the steam, in the filler, expands and fills out the compacted, and matted filler and renders the same light and fluffy. After the filler has been. thoroughly steamed the loaded shelves are removed and inserted into the curing, or drying, chamber 4 and rest on the side ledges 15 therein. This curing chamber has a heating coil 16 in the bottom thereof to supply heat thereto for curing purposes and its door 6 has an air inlet 17 near the bottom thereof, with a pivotally mounted blow fan disposed inside of the door. 6 so as to draw air in through the opening 17 and distribute the same throughout the chamber 4. so as to throughly dry and cure the filler therein.

The doors 5, 6 are kept closed during the steaming and curing process and the chambers 3, l, have the top openings 19, 20, re-

spectively, which may be controlled by the valve like shutters 21, 22. These shutters may be manually moved into open or closed position by the respective shift rods 23, 24;

While I have shown what I now consider the preferred form of the invention and the method of using the same it is contemplated that desirable changes may be made therein within the scope of the appended claims.

lVhat I claim is 1. A device of the character described having two chambers, foraminated shelves spaced apart vertically in said chambers, transverse nozzle pipes between the shelves formin means for deliver-in steam under Y b V b pressure, agamst the under sldcs of the shelves in one chamber, each chamber having a top opening and means for controlling said openings.

2. A device of the character described comprising separate closed compartments, shelves in each compartment spaced apart vertically, an upstanding inlet'manifold on each side of one compartment, transverse nozzle pipes connected into said manifolds and located between the corresponding shelves and provided with nozzle openings directed toward the undersides'of the corresponding shelves above.

8. The process of reconditioning fibrous material consisting in arranging said material in separate quantities in a closed chamber, introducing hot steam into said chamber between said quantities and circulating said steam through the separate quantities, and thereafter circulating hot dry air through said separate quantities of said material in a closed compartment.

4. A device for reconditioning lint cotton, comprising a chamber, a door at one end thereof, upstanding manifolds within the chamber, one on each side, steam nozzle pipes extending from each manifold in opposite directions, said nozzle pipes being spaced apart along the corresponding manifold and lying adjacent the corresponding chamber wall, each nozzle pipe being provided with an inside row of upwardly directed nozzle openings, side ledges arranged between the respective nozzle pipes whose inner ends are anchored to the corresponding wall of the chamber, standards supporting the forward, or

outer ends of said ledges, and removable foaminated shelves supported on said respective ledges.

5. A device for reconditioning lint cotton, comprising a chamber, a door at one end thereof, upstanding manifolds within the chamber, one on each side, steam nozzle pipes extending from each manifold. in opposite directions, said nozzle pipes being spaced apart along the corresponding manifold and lying adjacent the corresponding chamber wall, each nozzle pipe being provided with an inside row of upwardly directed nozzle openings, side ledges arranged between the respective nozzle pipes whose inner ends are anchored to the corresponding wall of the chamber, standards supporting the forward, or outer ends of said ledges, removable foraminated shells supported on said respective ledges, and a valve controlled opening in the top of the chamber.

In testimony whereof I have signed my name to this specification.

WILLIAM H. STINNETT.
